I'm really sorry and I can definitely relate to your fears. I have sinus trouble too and I keep putting off having the CT scan because I have to remain still and that freaks me out (my phobia relates to being confined).

Are you able to take something (a benzo) before you go and have someone accompany you? I really hope the procedure goes as well as possible. I know that sinus issues are a big pain (literally) so if the end result is no more sinus issues then that is definitely something very positive to focus on.

Good luck!! ((((((Billi))))))) Please let us know how it goes.
